Seems like a test with loadtxt is failing, which is odd since I've never touch this function or module.

Thank you for this PR @loiseaujc, LGTM. I think it is useful to expose these generalized LAPACK error handling routines in a more structured way.

Tried everything, but we will never understand what's going on with loadtxt (though I suspect some open file/ concurrency issues when tests are run with openmp or multithreaded)
